Hi,
I have a small blog application, and I would like to shorten its routes.
Here they are:
Blog::Application.routes.draw do
resources :categories do
resources :articles do
resources :comments
end
end
A rake routes command produce the following lines:
GET
/categories/:category_id/articles/:article_id/comments(.:format)
{:controller=>“comments”, :action=>“index”}
category_article_comments POST
/categories/:category_id/articles/:article_id/comments(.:format)
{:controller=>“comments”, :action=>“create”}
new_category_article_comment GET
/categories/:category_id/articles/:article_id/comments/new(.:format)
{:controller=>“comments”, :action=>“new”}
GET
/categories/:category_id/articles/:article_id/comments/:id(.:format)
{:controller=>“comments”, :action=>“show”}
PUT
/categories/:category_id/articles/:article_id/comments/:id(.:format)
{:controller=>“comments”, :action=>“update”}
category_article_comment DELETE
/categories/:category_id/articles/:article_id/comments/:id(.:format)
{:controller=>“comments”, :action=>“destroy”}
edit_category_article_comment GET
/categories/:category_id/articles/:article_id/comments/:id/edit(.:format)
{:controller=>“comments”, :action=>“edit”}
GET
/categories/:category_id/articles(.:format)
{:controller=>“articles”, :action=>“index”}
category_articles POST
/categories/:category_id/articles(.:format)
{:controller=>“articles”, :action=>“create”}
new_category_article GET
/categories/:category_id/articles/new(.:format)
{:controller=>“articles”, :action=>“new”}
GET
/categories/:category_id/articles/:id(.:format)
{:controller=>“articles”, :action=>“show”}
PUT
/categories/:category_id/articles/:id(.:format)
{:controller=>“articles”, :action=>“update”}
category_article DELETE
/categories/:category_id/articles/:id(.:format)
{:controller=>“articles”, :action=>“destroy”}
edit_category_article GET
/categories/:category_id/articles/:id/edit(.:format)
{:controller=>“articles”, :action=>“edit”}
GET /categories(.:format)
{:controller=>“categories”, :action=>“index”}
categories POST /categories(.:format)
{:controller=>“categories”, :action=>“create”}
new_category GET /categories/new(.:format)
{:controller=>“categories”, :action=>“new”}
GET /categories/:id(.:format)
{:controller=>“categories”, :action=>“show”}
PUT /categories/:id(.:format)
{:controller=>“categories”, :action=>“update”}
category DELETE /categories/:id(.:format)
{:controller=>“categories”, :action=>“destroy”}
edit_category GET /categories/:id/edit(.:format)
{:controller=>“categories”, :action=>“edit”}
As can be seen, each resource is ordered in a tree. So I believe that,
it’s could be interesting to simplify my routes such as for example:
/categories/ => /
/categories/:id => /:id
/categories/:category_id/articles/ =>
/:category_id/articles
/categories/:category_id/articles/:id =>
/:category_id/:id
/categories/:category_id/articles/:article_id/comments/ =>
/:category_id/:article_id/comments
/categories/:category_id/articles/:article_id/comments/:id =>
/:category_id/:article_id/:id
It’s more DRY, is’t it? 
Does Rails 3 provides a easy way to do so, with an HTTP verbs mapping to
controller actions automatically?
Thanks anyone.
